[vtkusers] Is it possible to move each pixel using a 3x3/4x4 matrix in VTK?

[Dženan Zukić]

It is not clear what you are trying to accomplish. Is it 2D image or 3D
image? If you need to display in a different place in some 3D space, then
you need to change image's transformation matrix, not the image itself.
